Abstract
In this study anodic stripping voltammetry was used to assess the contents of Cd, Cu, Mn and Zn in caviar of Acipenser persicus caught from Southern Caspian Sea sampling site. The ranged (μg g−1) of metals in caviar samples were: 0.025 to 0.069 for Cd, 1.08 to 1.76 for Cu, 0.009 to 0.01 for Mn and 12.9 to 21.1 for Zn, respectively. These levels are significantly lower than the adverse levels for human consumption based on FAO/WHO permissible limits. Therefore, caviar's contribution to the total body burden of these heavy metals can be considered as negligibly small, especially given that caviar is a luxury product. The result of the one-way analysis of variance suggested significant variations (p
